Septentrio unveils GNSS receivers for challenging environments

Septentrio, a division of Hexagon, has introduced two new products, the AsteRx RB3 GNSS receiver and the AsteRx RBi3 GNSS/INS system. These receivers are designed to operate in extreme environments, featuring IP69K-rated housings and components that have undergone rigorous ISO-standard testing.

The technologies robust construction ensures durability under heavy shocks, vibrations and challenging environmental conditions, making them suitable for demanding applications such as construction, mining and port automation.

The AsteRx RB3 and RBi3 utilize multi-frequency GNSS technology to deliver precise, centimeter-level positioning even in environments where GNSS signals are typically difficult to maintain. The receivers can be mounted externally on heavy machinery or integrated into chassis systems, offering flexibility in placement and simplifying installation.

The AsteRx RBi3 incorporates FUSE+ technology, which combines a high-performance GNSS engine with an industrial-grade inertial sensor. This integration provides accurate orientation data — such as heading, pitch and roll — alongside reliable positioning. In dual-antenna configurations, the receivers deliver sub-degree GNSS heading accuracy immediately upon initialization.

The AsteRx RB3 and RBi3 are ideal for machine guidance in industries requiring rugged equipment capable of maintaining precision under extreme conditions.
